Analog Devices Inc./Maxim Integrated MAX17580EVKIT#

Overview

MAX17580EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX17580 high-voltage, synchronous, inverting DC-DC converter. It delivers a regulated -5V output at up to 300mA from a 16V–55V input, operates at 600kHz switching frequency, supports programmable UVLO and soft-start, and complies with CISPR 32 Class B conducted/radiated emissions standards for industrial power design validation.

For engineers reviewing the MAX17580EVKIT# datasheet, MAX17580EVKIT# pinout, MAX17580EVKIT# application, or MAX17580EVKIT# equivalent, this kit enables rapid characterization of inverting buck-boost topology performance-including load/line regulation, efficiency across 15mA–300mA, startup/shutdown behavior, EMI filtering implementation, and external clock synchronization-under real-world PCB layout and thermal constraints.

Technical Context

The MAX17580EVKIT# implements the MAX17580ATC+ (12-pin TDFN, 3mm × 3mm) configured for discontinuous conduction mode (DCM) to maximize light-load efficiency. It features a fixed -5V output set by FB resistor divider (R203 = 154kΩ, R204 = 34kΩ), 600kHz operation via RT/SYNC resistor (R205 = 10.5kΩ), and active-low open-drain RESET asserted after 1024 switching cycles when VOUT2 reaches ≥95% of target.

Hardware-level design support includes system-ground-referenced EN/UVLO and RESET pins, adjustable soft-start (C212 = 5600pF yields ~1ms), optional EMI filter footprints (L202, C205), hot-plug input protection (C208 = 22μF/80V), and inductive short-circuit protection pads (R207/D201). Layout follows proven EMI-optimized routing with dedicated ground planes and minimized high-di/dt loop areas.

FAQ

What is the primary function of the MAX17580EVKIT#?

The MAX17580EVKIT# is a ready-to-use evaluation platform for the MAX17580 synchronous inverting DC-DC converter. It provides a fully assembled, tested, and EMI-optimized PCB that generates a regulated -5V output at up to 300mA from inputs between 16V and 55V. Engineers use the MAX17580EVKIT# to verify performance metrics-including efficiency, transient response, RESET timing, and compliance-before integrating the MAX17580 into final designs.

Can the MAX17580EVKIT# be used to evaluate other ICs besides the MAX17580?

No-the MAX17580EVKIT# is specifically configured for the MAX17580ATC+ IC (U201 on the board) and its associated -5V output architecture. While it shares physical PCB real estate with the MAX17579EVKIT# section, the two circuits are electrically isolated and independently powered. The MAX17580EVKIT# cannot evaluate the MAX17579 or any other device without hardware modification, which voids its validated performance claims and EMI certification.

How is the output voltage set and verified on the MAX17580EVKIT#?

The MAX17580EVKIT# output is factory-set to -5V using a precision FB resistor divider (R203 = 154kΩ, R204 = 34kΩ) per the MAX17580 datasheet. Output accuracy is confirmed by measuring VOUT2 relative to GND2 with a DMM: typical readings range from -4.95V to -5.05V across 15mA–300mA loads and 16V–55V input voltages, as shown in TOC04 load/line regulation plots.

Does the MAX17580EVKIT# support external clock synchronization?

Yes-the MAX17580EVKIT# includes dedicated RT/SYNC PCB pads (labeled RT/SYNC2) and a populated 10.5kΩ resistor (R205) to configure the internal oscillator at 600kHz. An external clock signal (660–840kHz) can be applied to synchronize multiple converters and reduce beat frequencies. Performance data (TOC20) confirms stable operation with 840kHz sync while maintaining phase margin >66° and gain crossover at 46.4kHz.

What safety and protection features are implemented on the MAX17580EVKIT#?

The MAX17580EVKIT# incorporates overcurrent protection (OCP), overtemperature shutdown (OTP), and input undervoltage lockout (UVLO) as inherent functions of the MAX17580IC. Hardware-level safeguards include hot-plug input damping (C208 = 22μF/80V), optional EMI filter footprints (L202/C205), and inductive short-circuit protection pads (R207/D201). All protections are validated in test reports (TOC21–TOC22).
